[PATCH] x86: kprobes: Remove remove bogus preempt_enable

[Thomas Gleixner]

The CONFIG_PREEMPT=n section of setup_singlestep() contains:

    preempt_enable_no_resched();

That's bogus in the CONFIG_PREEMPT=n section and it just never blew up
because preempt_enable_no_resched() is a NOP there. Remove it.
